The monsoons in Goa are magical and gives you the best of the Konkan coast. The amazing greenery and clouds in this season brings a totally different side of Goa in Monsoons
The Landscape in this season when traveling by road from Bombay to Goa or from Bangalore side is lush with greenery. 
Although you will miss most of the action on the beach in this season but the roads and villages will compensate you for this. 
Can you suggest the places that we should see if we have only 1 day in goa? we will be visiting next week
